Sea Ray 280 Br prop suggestions
 

I have a Sea Ray 280 Br with twin 5.7 EFIs and 19" Vengance props. Any suggestions for more speed? Im doing 49 at 4800rpm and the top end feels pretty strong. Could I go to a 21"? I am also getting ventilation in hard turns and need to fix that. Im hoping it's just from a busted up skeg.

Thanks!

You are near max rpm for the motor with the existing props. Adding pitch will load the motor to a lower hp band. You will likely suffer on top end. If you were bouncing off the rev limiter or hitting it hard then yes more pitch might be warranted.

A four blade prop with a little less pitch may help the ventilation issue but compromise top end slightly.
